How can I add attributes to a feature class?

JackFairfield — Mon, 05 Mar 2018 17:22:53 GMT

I have a feature layer of points whose only attribute is an ID that matches up to a table of data. How can I perform a "join" on the client side using the esri javascript api 4.x version so that the attributes from the corresponding table row exist in the feature layer and I can set definition expressions and use the attributes in popups.

Jack,

Look here:

This looks amazing. Thank you so much for the pointer Robert. I'll give it a shot and post back with my experience.

Do you happen to know where I can find the 'workspaceId' and 'dataSourceName' properties to use in this solution? I can't seem to find them through the ArcGIS Server Manager.

Jack,

Sounds like you are unfamiliar with dynamic workspaces.

The table must exist in a registered dynamic workspace in your Map Server.

Ok, this makes sense. I have registered my sde and I am using the Workspace ID that I created. Now how can I find the dataSourceName property? I would assume it would just be the name of the table on our sql server. But this doesn't seem to be working for me. Do I need to add anything? Maybe the schema (dbo.tableName) or something?

Thanks again for all your help.

Jack,

This is a example MAP.user1.TaxLots = workspaceid.User.FeatureClassName
